Applications Welding of LPG tankers, LPG storage tanks equipment for low-temperature service, and off-shore
structures to be used at low-temperature districts.
Characteristics 1. LC-318NH is a low hydrogen type covered electrode to be used in all-position welding of
aluminum-killed steel for low-temperature service and with good crack resistibility.
2. It provides excellent notch toughness at -45℃ and good usability in direct current welding.
Notes on usage 1. Welding heat input must be controlled in order to get required impact value, since notch
toughness tends to be decreased by excessive heat input.
2. Preheat at 50~100℃ is needed depending upon the kind of steel and its thickness.
3. Adopt back step method or strike the arc previously on a small steel piece to prevent
blowholes at the arc striking in a groove.
4. Dry the electrodes at 350-400℃ for about one hour before use.
